Really Good but needs a tiny improvement

Hello Khan Academy devs,
First of I would like to thank you for making such an amazing app which has been helping a lot to me. Personally I use it daily after my online classes and it is just more than a revision, while studying with khan academy it gives me much more knowledge which is helpful for me apart from the school curriculum, But I think more topics should be added to the app like some important topics are missing from the app (or atleast from my region). I get results for most of the things that I search on the app to study almost like 90% , but the important part is that remaining 10% is the part which you wish was on the app cause its that 10% which is the most focused in the Indian Syllabus and is asked most of the time in exams, so I would just like the devs to go through the Indian syllabus and add the missing topics to the app or the website. Apart from that the app is great and I recommend everyone to use it to gain a good chunk of knowledge for your life.

Useful app and scope to add further

My both kids are using the app and thanks for developers keeping them free and adding more courses. I would like to see foundation courses like CPT, CLAT and other courses subjects related to CA, ICWA which will help students a lot. Apart from course, I see lot of Indians have good knowledge but struggle on English speaking. So any course that can help English speaking and neutralise English will help a lot. Many of this essential course neither accessible nor affordable for them, but apps like this with low cost internet it will help all students , irrelevant of their status, education, location.

Thanks again and keep improving the product, please also try to include option to donate in local currency like INR.
